Election analyst Nate Silver said Monday that prediction markets may be undervaluing Democrats’ chances of reclaiming control of the House of Representatives in the 2026 midterm elections, while suggesting the battle for the Senate remains considerably more competitive.
Silver shared his latest outlook during an appearance on the All-In Podcast, where he discussed how current political conditions could shape next year’s congressional races.
According to Silver, prediction markets currently place Democrats’ chances of winning back the House at roughly 80% to 85%, while giving them a 40% to 45% probability of capturing the Senate. Although he described those estimates as generally reasonable, he argued the House numbers are slightly too conservative.
Silver said his own projection gives Democrats an 85% to 90% chance of retaking control of the lower chamber.
“The House is the one where kind of everything points in the same direction,” Silver said. “Democrats are facing a very unpopular president and an economy that voters have a lot of anxiety about.”
Silver pointed to several additional developments that he believes could work in Democrats’ favor. Among them, he cited President Donald Trump’s decision to begin the Iran war, the historical tendency for the party occupying the White House to lose ground during midterm elections, and what he described as recent “incumbent backlash” both in the United States and internationally.
While acknowledging that Republicans stand to benefit from congressional redistricting, Silver argued those gains may not be enough to overcome broader political trends.
“Look, the redistricting helps the GOP in the end, but you’re fighting against a lot of gravity,” he said.
Silver’s remarks referenced estimates that Republicans could gain between 10 and 16 House seats through redistricting victories. The GOP also received another favorable development on Monday when the Colorado Supreme Court rejected three Democrat-backed ballot measures that would have produced several additional congressional districts favorable to Democrats.
Election law also saw a significant development Monday when the U.S. Supreme Court ruled against President Trump on the issue of mail-in voting.
The court determined that states may continue counting mail-in ballots received after Election Day, provided those ballots were postmarked on or before Election Day.
Trump has long advocated for changes to election procedures, including requiring voter identification and limiting the use of mail-in ballots.
While expressing confidence in Democrats’ prospects for the House, Silver said control of the Senate remains far less certain.
He argued that Democrats are creating what he described as an “unnecessary risk” in Maine by backing Senate candidate Graham Platner, whom he characterized as scandal-plagued.
Silver suggested Maine is typically a state Democrats should expect to win in most election cycles, but said the party’s choice of nominee could make the contest more difficult than it otherwise would have been.
Although Silver believes Democrats hold a stronger position in the race for the House, he indicated that the Senate map presents a more challenging political landscape, with individual candidate quality likely to play a much larger role in determining the final outcome.
